This Gilbert tambour was supposed to go home tomorrow. It was only after I got it in its case that I noticed that the hands move too easily, which means that the cannon pinion has cracked. Okay, fine. But I can't get the plates apart because the little half-hour trip arm was secured to the rear of the minute arbor with tightly wound brass wire and has defied my every effort to remove it . I've worked on several of these clocks and never got stuck here. Any ideas?
